Perfect for my drone build
These bearings spin very smoothly and the flange helps keep them seated properly in the motor mount. Great quality for the price.

Good value overall
Most of the bearings were perfect. One was a little tight out of the box but loosened up after some use. Would buy again.

Exact replacement
Fit my 3D printer idler perfectly. The flange size matches the original specs exactly. Very satisfied with this purchase.
Q: What is the dynamic load rating?
A: The load rating varies by specific model number (e.g., F608 vs F603). Please refer to the manufacturer specification sheet for the specific size you need.
Q: What is the difference between ZZ and 2RS seals?
A: ZZ bearings have metal shields on both sides which offer less friction but less protection from dust. 2RS bearings have rubber seals which offer better protection but slightly higher friction.
Q: Do you offer bulk discounts for larger orders?
A: Yes, please contact our sales team directly through the customer service portal for pricing on bulk quantities over 50 packs.
Q: Are these metric or imperial sizes?
A: All bearings in the F603 series are metric sizes. Please check the specific product variation for exact dimensions.
Q: Are these suitable for high RPM applications?
A: Yes, these are designed for high-speed rotation commonly found in motors and spindles, though specific max RPM depends on the exact size selected.
